Re: Which-function-mode is turning itself off

[Richard Stallman]

    Don't quite know, except that there really isn't much reason to
    turn it off because of an error...

I did that to fix a really disastrous bug
which led to a loop getting errors.

    Does it really make sense for input-pending-p to run timers?

That is a good point.  Logically speaking, input-pending-p should not
run timers, since it does not wait.

It runs timers because of a change I made in 1996.  I went to a
certain amount of trouble to make this possible, so I must have
intended this result.  But I don't remember why.

It could be that correctly testing for whether input is pending
requires, in some cases, running the timers.  But that is only
a guess.  Does anyone know that code well enough to figure out
whether this is true?

We could just turn this off and see.
